Solving Chart Menu
A solving chart can be used to help you solve the puzzle by organizing the information given in the clues. Click on the boxes to cycle through an X (definitely no), Y (definitely yes), ? (maybe) and empty (unsure).
Clear Grid: Use this option to clear the form of all X's and Y's.
Form On Top: If you would like to keep the chart so that it is always visible, select this option. To reverse
this action, select it again.
Print: If you would rather print out the chart, select this option.
